Self-elevating type hanging bracket device for mounting steel tower and construction method for steel tower

Abstract

The invention relates to a self-elevating type hanging bracket device for mounting a steel tower and a construction method for the steel tower, and belongs to the application field of traffic engineering technology. The self-elevating type hanging bracket device for mounting the steel tower comprises a hanging bracket body, a hoisting machine tool, a vertical climbing machine tool used for driving the hanging bracket body to ascend and descend axially and vertically relative to the steel tower in the mounting process, a longitudinal adjusting machine tool used for adjusting the front and back positions of a hoisted structural member of the steel tower, a transverse adjusting machine tool used for adjusting the left and right positions of the hoisted structural member of the steel tower. The construction method for the steel tower comprises the following steps: the self-elevating type hanging bracket for mounting the steel tower is mounted; the structural members of the steel tower are hoisted by the hoisting machine tool and lifted upwards slowly; the structural members of the steel tower are transported to the designed mounting positions, and are connected with as-built steel tower segments in a matched manner; the above steps are repeatedly carried out until all the structural members of the steel tower are mounted.

Description

technical field [0001] The invention relates to a hanger device for installing a self-elevating steel tower and a construction method for the steel tower, belonging to the application field of traffic engineering technology. Background technique [0002] At present, hoisting machines such as tower cranes or crawler cranes are usually used in the hoisting of components such as steel towers or steel anchor boxes in China. The installation of the tower crane requires a firm attachment device for the tower crane to ensure the stability of the tower crane. The installation of the crawler crane requires sufficient counterweight to balance the center of gravity of the crane. The labor intensity of the on-site operation is relatively large, and the risk factor of the on-site operation is large. At the same time, the above processes are adopted All adopt large-tonnage hoisting machinery, and the installation cost is high. Contents of the invention [0003] One of the purposes ...
